Online Energy Adjustment Using AR-HMM for Speech Enhancement

  title={Online Energy Adjustment Using AR-HMM for Speech Enhancement},
  author={He Yu-we},
Because the existing single channel speech enhancement technologies perform not w ell in the tracking and suppression of non-stationary noise,the speech enhancement method based on online energy adjustment is proposed.The normalized critical band energy parameters are employed as the feature in Gaussian mixture model( GM M) to distinguish the background noises.Based on the AR-HM M of clean speech and the noise of corresponding type,the pow er spectrums of speech and noise are estimated under… CONTINUE READING
